I think it can’t be distributed into portions. As long as there is an absence of seed and vegetable oils and processed food (I’d include anything low fat) the rest is so different for so many people at varying stages of age, fitness levels and what they are trying to achieve but I’d have an ‘eat with extreme caution’ clause on the carbs and a side note of not a necessary food next to them too.
There would have to be several plates too, depending on diets. Vegetarians are easier to cater for with their inclusion of dairy and vegans require specific information regarding a diet bereft of animal protein.
